Bavette, or Flap Steak, is an undiscovered delicacy. It is similar to Flank Steak, but plumper. Flap benefits from a tenderizing marinade.
Thoroughly thaw and dry your Otsquago Creek Flap Steak. Use paper towels to dry off your steak.
Season both sides of the Flap Steak with Salt and Pepper
Place all marinade ingredients in a Food Processer or Blender. Process/Blend until relatively smooth.
Using either a shallow dish or a ziplock bag, coat all sides of the Flap Steak with the prepared Marinade. Once coated, place back in the refrigerator for at least one hour and up to 12 hours.
Remove the steak 30 minutes before you intend to grill. Do your best to scrape off most of the marinade. (Because the marinade has olive oil in it, it will smoke and burn if you put too much of it on the grill.)
Heat up your grill - either charcoal or gas. Alternatively, if you do not have a grill, you can sear your Flap Steak in a piping hot skillet - if you have one that is big enough. Once your grill or skillet is up to temperature, grill/sear the steak for about 4-6 minutes per side. You can use a meat thermometer in the thickest part of the steak. 130℉ is considered Medium Rare.
When the steak is cooked to your preferred doneness, remove from the grill. Place on a warm cutting board and cover with foil. Let rest for 10-15 minutes so the steak can reabsorb juices released in the cooking process.
Slice thinly against the grain of the meat for optimal tenderness.
